![]() And experts stress that direct-air carbon capture is by no means going to give humanity a longer runway to phase out fossil fuels-if we want to have a livable climate in the next century. should “focus” on direct-air carbon capture that doesn’t involve enhanced oil recovery (one such plant opened in Iceland this year). They’re just people trying to make money, and they’re giving you nonsense.”ĭiech of Carbon180 thinks the U.S. ![]() “They’re not atmospheric scientists trying to do this. But Mark Jacobson, a professor of civil and environmental engineering and Director of Stanford University’s Atmosphere/Energy program, doesn’t think that Oldham’s climate-friendly oil scenario is possible. Oldham, whose company plans to use captured CO2 for enhanced oil recovery at a facility in Texas’s Permian Basin, slated to open in 2024, says that oil will be essentially carbon negative, as the facility will capture and store more CO2 than is contained in the oil it extracts (Oil companies Chevron and Occidental Petroleum are substantial investors in Carbon Engineering). He is certain, however, that we should not support carbon removal projects that use captured CO2 to help produce more oil. “What we don’t know is which approaches are likely to be the most promising,” says Higdon. Direct-air capture is one way to do that biomass (for instance, planting trees) could be another. climate policy at the Environmental Defense Fund, notes that the world will likely need to find a way to pull billions of tons of carbon out of the atmosphere in the next 30 years. “It’s really crystalized for people at the company that what we’re doing here is very significant,” says Oldham. But for Carbon Engineering, Oldham says the government funding is something of a confirmation that they’re on the right track. To make a dent in climate change, the world would have to be sequestering thousands of times more carbon dioxide than those projects will annually. Those projects will be similar to the scale of privately funded facilities planned by Carbon Engineering in the coming years. The direct-air capture hubs funded by the infrastructure bill would each be able to pull a million tons of CO2 out of the air every year, though the details of who will be building those hubs isn’t clear yet. These CCS approaches (which also will get funding through Biden’s infrastructure bill) have a much longer track record than direct-air capture, which has long been seen by many experts as an ambitious idea but unlikely to scale to the point where it’d be worth the investment. Most carbon capture and storage (CCS) technologies in use and development grab carbon produced by industrial sources like power plants before it enters the atmosphere.
